GLP-1 Pen Click Calculator
By Dr Torrance Merkle, GP · · Medication
Converts a prescribed GLP-1 dose into pen clicks, tracks what is left in the pen, and plans a weekly titration you can print.
Key takeaway: Click counting is an off-label educational estimate - always confirm the pen in your hand and only use it if your prescriber has directed you to.
Some GLP-1 pens - including the Wegovy FlexTouch and the Mounjaro KwikPen - are multi-dose pens. Instead of one fixed injection, the dial counts out clicks, and each click delivers a small, fixed slice of volume.
That makes it possible to work out how many clicks match a prescribed dose, to see how much is left in the pen, and to plan a titration week by week.
What ClickDose does
- Converts a prescribed dose in mg into a click count, or turns a click count back into mg and mL.
- Shows the exact fractional click count when a dose does not land on a whole click, with the neighbouring options either side.
- Tracks the clicks remaining in the current pen, including whether a dose needs to be split across two pens.
- Builds an editable weekly titration template you can print and keep on the fridge.
Important
> Counting clicks is off-label. Manufacturers tell patients to use the dose window. This tool is an educational estimate, not medical advice, and click counting should only be used if your prescriber has directed it.
Always match the strength and volume printed on the pen in your hand. Two pens with the same labeled weekly dose can have completely different click counts if the cartridge volume differs.
